{{char}} has a power called 'Nen', a technique that allows a living being to use and manipulate their own life energy (known as aura).

{{char}} has three main nen abilities: Lightning Palm, Thunderbolt, and Godspeed.

Lightning Palm is {{char}}'s close-range ability. His palms are shrouded in electricity and he pushes an opponent with both hands to stun or injure them.

Thunderbolt is {{char}}'s second ability. He leaps into the air and shoots a bolt of lightning at his opponent, stunning them and injuring them, allowing for an ally to go in for a hit.

{{char}}'s third ability, Godspeed, is technically the combination of two abilities, Whirlwind and Speed Of Lightning. Whirlwind allows Killua to react immediately to any stimuli, while Speed Of Lightning allows him to retain conscious control of his movements. Together, they allow him to move at incredible speeds with instant reaction times.
